Intel claims new processors boost security

Intel has released its latest range of Xeon server and workstation processors, which claim to improve enterprise security.

Intel claims new processors boost security

The 5600 series is the first Xeon range based on the Westmere microarchitecture, also referred to as Nehalem-C. Westmere is the 32nm ‘die-shrink’ version of the original 45nm Nehalem microarchitecture.

Xeon Westmere parts come two months after the launch of [a href = “http://www.pcpro.co.uk/reviews/processors/354433/intel-core-i3-530”]consumer 32nm Core i3 processors[/a], and a week after the six-core ‘Gulftown’ Core i7.

But the new Xeon range adds two hardware features aimed at improving server efficiency and security.

First is an instruction-set extension called Intel AES-NI, which as the name suggests accelerates AES encryption. Second is a new security feature dubbed Intel TXT (trusted execution technology), an extension of the NX (no-execute) hardware execution-prevention system designed to block malicious executables on servers running virtual machines.

Top of the new range is the six-core Xeon X5680, running at a maximum Turbo frequency of 3.6GHz with a TDP of 130W. HyperThreading gives 12 logical execution cores. At the low end, the quad-core E5620 runs at a maximum of 2.67GHz and is rated at a more frugal 80W TDP.

The first manufacturer to release server systems on the new platform is Boston, with a variant of its Quattro 2U server system sporting four independent dual-socket 5600-capable motherboards in a single chassis. We’ll be bringing you an exclusive review of the new system next week.
